上述目的係藉由本發明之氣溶膠吸引器而達成，該氣 溶膠吸引器係具備：氣溶膠產生流路，從外部空氣導入口 延伸至管口；液供給裝置，具有貯積屬於氣溶膠之原料之 溶液的液室，並且可將預定量之溶液從該液室供給至氣溶 膠產生流路所規定之供給位置；加熱裝置，係為位在供給 ® 位置之下游且配置於氣溶膠產生流路的加熱裝置，對在該 氣溶膠產生流路中流動之溶液進行加熱而使其蒸發，該溶 液係當氣溶膠產生流路内之空氣透過管口被吸引，而在氣 溶膠產生流路内產生吸引空氣之流動時，隨著該吸引空氣 之流動而從供給位置往管口移送者，而產生溶液之氣溶 膠；以及保護器，設置在從該加熱裝置經由供給位置到達 液供給裝置的路徑，並由周圍之環境保護位於供給位置及 ❹ 液室内的溶液。 具體而言，保護器係包含配置在供給位置之附近，且 用以減低從加熱裝置傳達至供給位置之熱的減低裝置。此 時，減低裝置係具有包圍氣溶膠產生流路之散熱構件。 依據上述氣溶膠吸引器，加熱裝置係在吸引動作時， 在原料溶液從供給位置往管口移送之過程中，加熱原料溶 液並使之蒸發，而使氣溶膠產生。 即使在為了使氣溶膠吸引器能夠使用，而使加熱裝置 恆常運作中，從加熱裝置傳達至供給位置的熱亦透過減低 4 320811 200932367 裝置（即散熱構件）散熱，供給位置的周圍溫度係維持在溶 液不會揮發的溫度以下。 保護器係可取代減低裝置，或可包含減低裝置與冷卻 - 裝置。 另一方面，保護器係可取代上述減低裝置與冷卻裝 置，或除了包含減低裝置與冷卻裝置以外，亦可包含配置 在供給位置與前述液供給裝置之間的閥。此時，閥係僅在 氣溶膠產生流路内之空氣透過管口而被吸引時打開。 Ο ~ 該閥係在供給位置與液供給裝置之間，可將液供給裝 置之液室對於外部進行密封，而從周圍之環境保護液室之 溶液。 具體而言，閥係包含：可彈性變形的管，連接供給位 置與液供給裝置，且其内部之一部分形成為閥通路；及可 動構件，設置在該管之附近，使管彈性變形並壓潰，且可 在關閉閥通路之閉位置、與遠離前述管而打開閥通路之開 @ 位置之間移動。 此時，閥復可包含：固定構件，與可動構件一同作用， 而可夾持管；閥彈簧，將可動構件朝閉位置彈壓；及致動 器，使可動構件抵抗該閥彈簧之彈壓力而移動至開位置。 具體而言，致動器係具有安裝在可動構件之磁鐵、及 可吸附磁鐵之電磁線圈，或致動器係由形狀記憶合金所形 成之控制彈簧。 (發明之效果） 氣溶膠吸引器之保護器係從周圍之環境保護供給至供 5 320811 200932367 給位置之溶液或液供給裝置之液室内的溶液，並阻止溶液 之揮發或變質。因此，藉由液供給裝置而被供給至供給位 置的溶液之全量會成為氣溶膠，而由使用者所吸引，因此 - 關於氣溶膠之產生量，保證其定量性和品質。 【實施方式】 參照第1圖，第1實施例之氣溶膠吸引器係具備外殼 (未圖示）。該外殼係在其前端具有外部空氣導入口 2,另 一方面，在其後端具有管口 4，該管口 4係從外殼突出。 ® 再者，外殼係在其内部規定氣溶膠產生流路6，該氣溶膠 產生流路6係從外部空氣導入口 2延伸至管口 4。具體而 言，在該實施例之情形時，氣溶膠產生流路6之一部分係 藉由空氣導入管8及管狀之陶瓷加熱器12所形成。 空氣導入管8係由不鏽鋼所形成，且形成階梯形狀。 亦即，空氣導入管8係具有位於外部空氣導入口 2侧之大 徑部、及位於管口 4侧之小徑部。空氣導入管8之小徑部、 q 亦即下游端係經介環狀之連結器10連接在陶瓷加熱器 12。更詳細而言，空氣導入管8之下游端係挿入陶瓷加熱 器12之上游端，該等下游端及上游端係形成有接頭部。連 結器10係從外侧圍繞接頭部，且氣密地連接空氣導入管8 及陶瓷加熱器12。 從空氣導入管8延伸出有液管路16，該液管路16之 一端係在供給位置A連接於空氣導入管8之大徑端部、即 上游端部。液管路16之另一端係連接在可搬型之液供給裝 置18，該液供給裝置18係在其内部具有貯積溶液之液室 6 320811 200932367 (未圖示），可從該液室通過液管路16，以每次一定量之方 式對供給位置A供給溶液。因此，在使用吸入器之前，液 供給裝置18係預先運作，而液管路16内係以溶液充滿至 -供給位置A。具體而言，液供給裝置18係包含具有作為前 述液室之泵室的注射泵（syringe pump)、及驅動該注射系 之驅動源。 再者，在空氣導入管8之外側，配置有鋁製之散熱罩 20,該散熱罩20係覆蓋具有供給位置A之空氣導入管8的 〇 上游端部。具體而言，散熱罩20係形成中空之圓筒形狀， 且具有空氣導入管8之上游端部所貫穿之閉塞端、及朝空 氣導入管8開口之開口端。散熱罩20係具有比空氣導入管 8的上游端部之外徑更大的内徑、及覆蓋其外表面之全區 域的被覆層（未圖示），該被覆層係藉由黑色防蝕鋁 (Alumite)所形成。 再者，吸引器係分別具備陶瓷加熱器12用之電源開關 φ (未圖示）、及液供給裝置18用之手動操作型之液供給開關 (未圖示）。 由使用者對電源開關進行開啓操作時，陶瓷加熱器12 之溫度係上昇至運作溫度，然後保持在該運作溫度。在此 狀態下，由使用者對液供給開關進行開啓操作時，液供給 裝置18係運作，而將一定量之溶液通過液管路16從供給 位置A送出至氣溶膠產生流路6内。另一方面，使用者在 進行液供給開關之開啓操作的同時，透過管口 4吸引氣溶 膠產生流路6内之空氣，並且使從外部空氣導入朝管口 4 7 320811 200932367 的空氣流動（即吸引空氣流）在氣溶膠產生流路6内產生。 該吸引空氣流係將從供給位置A送出之溶液朝陶瓷加熱器 12移送。如此，當溶液到達陶瓷加熱器12内時，溶液係 - 藉由陶瓷加熱器12立即被加熱而蒸發，然後在吸引空氣流 中凝縮而成為氣溶膠，該氣溶膠係與吸引空氣一同被使用 者所吸引。 即使從供給位置A送出至氣溶膠產生流路6内之溶液 受到來自陶瓷加熱器12之熱，溶液之溫度上昇亦會因散熱 〇 罩20之作用而被抑制。因此，送出至氣溶膠產生流路6内 之溶液不會在供給位置A之附近立即揮發，而是藉由使用 者之吸引動作從供給位置A移送至陶瓷加熱器12後，其全 量才成為氣溶膠而被使用者所吸引。 若未具備散熱罩20，則從供給位置A送出之溶液係受 到來自陶瓷加熱器12之熱，其一部分揮發而從外部空氣導 入口 2逸散至外部。此時，使用者進行吸引動作時，即使 Q 液供給裝置18將一定量之溶液送出至氣溶膠產生流路6 内，使用者所吸引之氣溶膠的量亦不穩定。 陶瓷加熱器12之溫度上昇至300°C，且該狀態保持10 分鐘時，進行測定在供給位置A之溫度的實驗。在此，由 實驗結果發現，散熱罩20係將在供給位置A之溫度之上昇 抑制在約60°C，相對於此，未具備散熱罩20時，則在供 給位置A之溫度亦上昇至約160°C。 此外，實驗所使用之空氣導入管8、陶瓷加熱器12及 散熱罩2 0之尺寸係如下所述。 8 320811 200932367 空氣導入管8 : ^ 6mm小牷部之外徑=1· 9mm、長度= l5mm、厚度 = lmm 又 陶瓷加熱器12 : 〇咖外徑=4mm、長度=30腿、電阻値=〇. 4Ω 散熱罩20 : =面積=1160咖2、體積=412_3 空氣導人管8係取代前述散熱罩2() 2〇、熱管或熱容量大之埒比士 胥散…卓 ^ 大之政熱片。此時，熱管或散熱片係相 里人管8 ’以連接在供給位置A之附近者為佳。 如第1圖巾2點鏈線所示，在進行空氣導入管8之 =時’可制料⑽eltier)元件或氣冷或水冷等冷卻 器74 〇 第2圖係顯示第2實施例之氣溶膠吸引器。 ^在說明第2實施例之吸引器時，對與第}實施例之吸 © h之構成要素發揮同-功能之構成要素標記同一元件符 號’並省略其說明。 第2實施例之吸引器係具備開閉閥22,該開閉閥22 二-置在液g路16。再者，吸引器亦具備感測使用者所進 仃之吸！丨動作的壓力式之吸引感知感測器（未圖示）。當經 吸引感知感測器檢測出使用者所進行之吸引動作時，開閉 閥22即打g。相對於此’當吸引感知感測器未檢測出使用 者所進行之吸引動作時，開閉閥22即維持關閉之狀態。 再者，前述液供給裝置18亦依據來自吸引感知感測器 320811 9 200932367 之檢測信號而運作。此時，液供給裝置18係與使用者之吸 引動作連動，亦即由吸引感知感測器輸出檢測信號時，將 一定量之溶液從供給位置A送出至氣溶膠產生流路6内。 -在該時間點，實施溶液之送出時，溶液係從供給位置A立 即往陶瓷加熱器12移送，而成為氣溶膠。 如以上之說明得知，當使用者不進行吸引動作時，開 閉閥22即關閉。因此，不會有液供給裝置18之泵室内的 液透過外部空氣導入口 2或管口 4而曝露於外部空氣的疑 〇 虞，泵室係保持在密閉狀態。因此，泵室内之溶液包含香 料等揮發成分，且即使來自陶瓷加熱器12之熱傳達至泵室 内之溶液，而使揮發成分從溶液揮發，揮發成分亦不會放 出至外部空氣。結果，有效地防止泵室内之溶液的變質。 再者，在第1圖中，開閉閥22係以2點鏈線表示。這 是表示開閉閥22可與散熱罩20或冷卻裝置21併用。 開閉閥22可使用各種之市售的閥，例如液管路16由 Q 可彈性變形之橡膠管所形成時，亦可使用將該橡膠管之一 部分利用作為閥通路的開閉閥。該種開閉閥係藉由一邊使 橡膠管彈性變形，一邊進行壓潰，而關閉閥通路，另一方 面，解除橡膠管之壓潰，並藉由橡膠管之復原力而回復到 原來之狀態，以打開閥通路。 該種開閉閥之一例係如第3圖及第4圖所示。 第3圖之開閉閥24係具備固定板26、及從該固定板 26隔開之可動板28，固定板26亦可為前述外殼之内壁。 在固定板26與可動板28之間配置有一對之閥彈簧30，該 10 320811 200932367 等閥彈簧30係拉伸線圈彈簧。各閥彈簧30係連接在固定 板26及可動板28之雙方，並將可動板28朝固定板26予 以彈壓、亦即予以吸引。 -作為液管路16之橡膠管32係具耐熱性，並通過閥彈 簧30間而延伸。在此實施例時，橡膠管32係固定在固定 板26。由第3圖觀之，在可動板26之下面安裝有推進器 (pusher)34，該推進器34係藉由上述可動板28之吸引， 使橡膠管32彈性變形並將其壓潰。亦即，此時之開閉閥 ® 24係處於關閉橡膠管32、即關閉其閥通路之狀態。 另一方面，在可動板28之上面安裝有磁鐵36，並且 在可動板28之上方配置有電磁線圈（solenoid)38。從第3 圖所示之狀態來看，當電磁線圈38被激磁時，電磁線圈 38係朝上方吸引磁鐵36。因此，磁鐵36係抵抗閥彈簧30 之彈壓力，與可動板38及推進器34 —同上昇，如第4圖 所示，推進器34係從橡膠管32離開，而解除橡膠管32之 q 壓潰。結果，橡膠管32係藉由本身之復原力回復到原來之 狀態，而打開閥通路、即打開開閉閥24。 上述開閉閥24亦可與使用者之吸引動作或前述電源 開關之開啓操作連動而打開。 第5圖及第6圖係顯示變形例之開閉閥40。 開閉閥40係具備固定壁42，在該固定壁42固定有橡 膠管32。再者，固定壁42係與前述固定板26同樣地，亦 可為外殼之内壁。 在橡膠管32之附近配置有推桿44。該推桿44係相對 11 320811 200932367 於固定壁42垂直地延伸，且支持在桿支架46。更具體而 言，桿支架46係具有一對支持壁48a、48b，該支持壁48 係在推桿44之軸線方向相互地隔開。推桿44係分別可自 . 由滑動地貫穿支持壁48a、48b，且受該等支持壁48支持。 此外，推桿44係在其外周具有凸緣50，該凸緣50係 定位在一對支持壁48a、48b之間。在支持壁48a與凸緣 50之間，以圍繞推桿44之方式配置有不鏽鋼製之壓縮線 圈彈簧（亦即閥彈簧52)，該閥彈簧52係發揮與前述閥彈 ®簧30同樣之功能。 因此，閥彈簧52係經介凸緣50將推桿44朝橡膠管 32予以彈壓、即予以推出。因此，如第5圖所示，推桿44 係使橡膠管32彈性變形並使之壓潰，藉此，開閉閥40係 處於關閉之狀態。 另一方面，在凸緣50與支持壁48b之間，配置有壓縮 線圈彈簧、亦即控制彈簧54，該控制彈簧54係由形狀記 q 憶合金所形成。控制彈簧54之彈簧常數係依本身之溫度而 變化。更詳細而言，當處於周圍之溫度或本身之溫度低的 低溫環境時，控制彈簧54之彈簧常數係比控制彈簧52之 彈簧常數小，但當處於周圍溫度或本身之溫度高於預定値 以上之高溫環境時，控制彈簧54之彈簧常數係比控制彈簧 52之彈簧常數大。 再者，控制彈簧54之本身溫度係可藉由控制對控制彈 簧54之電力的供給而改變。 當開閉閥40處於低温環境下時，閥彈簧52係不管控 12 320811 200932367 制彈簧50之彈壓力，如前所述將推桿44朝橡膠管％推 出，如第5圖所示開閉閥40係處於關閉之狀態。此時，凸 緣50與支持壁48b之間的距離係以L1表示。 然而，當開閉閥40處於高温環境下時.，控制彈簧54 之彈壓力係比閥彈簧52之彈壓力大。因此，控制彈酱54 係將推桿44朝從橡膠管32離開之方向拉扯，如第6圖所 示，推桿44係解除橡膠管32之壓潰，藉此打開開閉閥4〇。 此時之支持壁48b與凸緣50之間的距離係以L2(>u)表 示。 如上所述，開閉閥40係依溫度環境而開閉，因此陶瓷 加熱器12會保持在運作溫度，開閉閥4〇因來自陶瓷加熱 器12之熱而處於溫度環境下時，開閉閥4〇即打開。相對 於此，陶瓷加熱器12未運作，而開閉閥4〇處於低溫環境 下時，開閉閥40即關閉。此時，開閉閥4〇係與前述電源 開關之開啓關閉操作連動而開閉。 ' © 此外，開閉閥40係與電源開關之開啓關閉操作不同 地，亦藉由控制對控制彈簧54之電力的供給而開閉，因此 亦可僅在使用者進行吸引動作時打開開閉閥4〇。 【圖式簡單說明】 第1圖係顯示第1實施例之氣溶膠吸引器的概略圖。 第2圖係顯示第1實施例之氣溶膠吸引器的概略圖。 第3圖係第2圖中之開閉閥在其閉位置的具體示意圖。 第4圖係第3圖中之開閉閥在其開位置的示意圖。 第5圖係變形例之開閉閥在其閉位置的示意圖。 320811 13 200932367 • 第6圖係第5圖中之開閉閥在其開位置的示意圖。 【主要元件符號說明】 2 外部空氣導入口 4 管口 6 氣溶膠產生流路 8 空氣導入管 10 連結器 12 陶曼加熱器 16 液管路 18 液供給裝置 20 散熱罩 21 冷卻裝置 22、 24、40 開閉閥 26 固定板 28 可動板 30、 52閥彈簧 32 橡膠管 34 推進器 36 磁鐵 38 電磁線圈 42 固定壁 44 推桿 46 桿支架 48、 48a、48b 支持壁 50 凸緣 54 控制彈簧 A 供給位置 Q LI、L2凸緣與支持壁之間的距離 14 320811200932367 VI. Description of the Invention: [Technical Field] The present invention relates to a method for supplying medicine to a user in the form of an aerosol (aer〇s〇l, a misty solution, which is called an aerosol by a general practitioner). An aerosol attractor such as a product or a hobby. [Prior Art] Ο The seed gas, the gluteal attractor is disclosed, for example, in Japanese Patent Publication No. 510763. The suction of the publication (4) includes a supply pump for supplying a solution (liquid material) of a raw material belonging to an aerosol, and the supply pump is connected to the tube. The tube system has a solution that is supplied from the supply fruit after the opening of the π end. Further, 'the front end of the tube is disposed adjacent to the nozzle 〇nc) Uthpiece), and is disposed in such a manner as to surround the front end of the tube. The electricity is added to the solution in the front end of the crying two and evaporates, and the vapor of the solution is automatically ejected. The vapor of the solution is condensed to form an aerosol by the air that is attracted by the user. Therefore, the user can simultaneously attract the aerosol and the inhaled air. SUMMARY OF THE INVENTION [Problem to be Solved by the Invention] In the use state of the attractor of the above publication, it is placed in the outside air, and the ice is heated through the official opening. Therefore, when the solution package is exposed to the volatile component from the electro-hydraulic solution due to the white X component, the dissolution in the tube will be thermally degraded, and each method will be degraded. Another quality. μ Stable to maintain the solution, that is, the aerosol 320811 200932367 The object of the present invention is to provide an aerosol aspirator capable of attracting aerosols of stable quality. (Means for solving the problem) - The above purpose is According to the aerosol aspirator of the present invention, the aerosol aspirator includes an aerosol generating flow path extending from the external air introduction port to the nozzle, and a liquid supply device having a storage genus a liquid chamber of the solution of the raw material of the aerosol, and a predetermined amount of the solution is supplied from the liquid chamber to a supply position defined by the aerosol generating flow path; the heating device is located downstream of the supply® position and disposed at a heating device for generating an aerosol path, wherein a solution flowing in the aerosol generating flow path is heated and evaporated, and the solution is attracted to the air in the aerosol generating flow path through the nozzle, and in the aerosol When a flow of suction air is generated in the flow path, the aerosol is generated from the supply position to the nozzle as the suction air flows, and the protector is disposed to reach the liquid from the heating device via the supply position. The path of the supply device is located in the supply position and the solution in the liquid chamber by the surrounding environmental protection. Specifically, the protector includes a heat disposed in the vicinity of the supply position and used to reduce the heat transmitted from the heating device to the supply position. The device is reduced. At this time, the reducing device has a heat dissipating member surrounding the aerosol generating flow path. According to the above aerosol attractor, the heating device During the suction operation, during the transfer of the raw material solution from the supply position to the nozzle, the raw material solution is heated and evaporated to generate an aerosol. Even in order to enable the aerosol aspirator to be used, the heating device is constantly used. During operation, the heat transmitted from the heating device to the supply position is also reduced by the heat dissipation of the device (ie, the heat dissipating member), and the ambient temperature at the supply position is maintained below the temperature at which the solution does not volatilize. The protector can replace the reducing device. Alternatively, the reducing device and the cooling device may be included. Alternatively, the protector may replace the reducing device and the cooling device, or may include a reducing device and a cooling device, and may be disposed between the supply position and the liquid supply device. At this time, the valve system is opened only when the air in the aerosol generating flow path is attracted through the nozzle. Ο ~ The valve is between the supply position and the liquid supply device, and the liquid chamber of the liquid supply device can be supplied For external sealing, the solution from the surrounding environmental protection liquid chamber. Specifically, the valve system includes: an elastically deformable tube connecting the supply position and the liquid supply device, and one of the inner portions thereof is formed as a valve passage; and a movable member disposed in the vicinity of the tube to elastically deform and crush the tube And moving between the closed position where the valve passage is closed and the open @ position that opens the valve passage away from the tube. In this case, the valve may include: a fixing member that acts together with the movable member to clamp the tube; a valve spring that biases the movable member toward the closed position; and an actuator that causes the movable member to resist the spring pressure of the valve spring Move to the open position. Specifically, the actuator has a magnet attached to the movable member and an electromagnetic coil capable of adsorbing the magnet, or the actuator is a control spring formed of a shape memory alloy. (Effect of the Invention) The protector of the aerosol attractor is supplied from the surrounding environmental protection to the solution in the liquid solution of the solution or liquid supply device for the position of 5 320811 200932367, and prevents the volatilization or deterioration of the solution. Therefore, the total amount of the solution supplied to the supply position by the liquid supply device becomes an aerosol and is attracted by the user. Therefore, the amount of aerosol generated is ensured to be quantitative and quality. [Embodiment] Referring to Fig. 1, the aerosol aspirator of the first embodiment includes a casing (not shown). The outer casing has an outer air introduction port 2 at its front end, and on the other hand, has a spout 4 at its rear end, which is protruded from the outer casing. Further, the outer casing defines an aerosol generating flow path 6 therein, and the aerosol generating flow path 6 extends from the external air introducing port 2 to the nozzle 4. Specifically, in the case of this embodiment, a part of the aerosol generating flow path 6 is formed by the air introduction tube 8 and the tubular ceramic heater 12. The air introduction pipe 8 is formed of stainless steel and formed in a stepped shape. In other words, the air introduction pipe 8 has a large diameter portion on the side of the outside air introduction port 2 and a small diameter portion on the side of the nozzle port 4. The small diameter portion of the air introduction pipe 8, q, that is, the downstream end, is connected to the ceramic heater 12 via a ring-shaped connector 10. More specifically, the downstream end of the air introduction pipe 8 is inserted into the upstream end of the ceramic heater 12, and the downstream end and the upstream end are formed with joint portions. The coupler 10 surrounds the joint portion from the outside and hermetically connects the air introduction pipe 8 and the ceramic heater 12. The liquid supply pipe 16 is extended from the air introduction pipe 8, and one end of the liquid pipe 16 is connected to the large-diameter end portion of the air introduction pipe 8, that is, the upstream end portion, at the supply position A. The other end of the liquid line 16 is connected to a movable liquid supply device 18, which is a liquid chamber 6 320811 200932367 (not shown) having a storage solution therein, and can pass liquid from the liquid chamber. The line 16 supplies the solution to the supply position A in a certain amount each time. Therefore, before the use of the inhaler, the liquid supply device 18 is operated in advance, and the liquid line 16 is filled with the solution to the supply position A. Specifically, the liquid supply device 18 includes a syringe pump having a pump chamber as the above-described liquid chamber, and a drive source for driving the injection system. Further, on the outer side of the air introducing pipe 8, a heat radiating cover 20 made of aluminum is disposed, and the heat radiating cover 20 covers the upstream end portion of the air introducing pipe 8 having the supply position A. Specifically, the heat dissipation cover 20 is formed into a hollow cylindrical shape, and has a closed end through which the upstream end portion of the air introduction pipe 8 is inserted, and an open end that opens toward the air introduction pipe 8. The heat dissipation cover 20 has an inner diameter larger than the outer diameter of the upstream end portion of the air introduction pipe 8, and a coating layer (not shown) covering the entire outer surface of the air introduction pipe 8, which is made of black alumite ( Alumite) formed. Further, the suction device includes a power switch φ (not shown) for the ceramic heater 12 and a manual operation type liquid supply switch (not shown) for the liquid supply device 18, respectively. When the user turns on the power switch, the temperature of the ceramic heater 12 rises to the operating temperature and then remains at the operating temperature. In this state, when the liquid supply switch is turned on by the user, the liquid supply device 18 operates, and a certain amount of the solution is sent from the supply position A to the aerosol generation flow path 6 through the liquid line 16. On the other hand, while the user performs the opening operation of the liquid supply switch, the air is sucked through the nozzle 4 to generate the air in the flow path 6, and the air is introduced from the outside air to the nozzle 4 7 320811 200932367 (ie, The suction air flow is generated in the aerosol generation flow path 6. This suction air flow transfers the solution sent from the supply position A toward the ceramic heater 12. Thus, when the solution reaches the ceramic heater 12, the solution is immediately heated by the ceramic heater 12 to evaporate, and then condensed in the suction air stream to become an aerosol, which is used by the user together with the suction air. Attracted. Even if the solution sent from the supply position A to the aerosol generating flow path 6 receives heat from the ceramic heater 12, the temperature rise of the solution is suppressed by the action of the heat radiation mask 20. Therefore, the solution sent to the aerosol generating flow path 6 does not immediately evaporate in the vicinity of the supply position A, but is transferred from the supply position A to the ceramic heater 12 by the suction operation of the user, and the entire amount becomes the gas. The sol is attracted to the user. If the heat sink 20 is not provided, the solution sent from the supply position A is heated by the ceramic heater 12, and a part of the solution is volatilized and escapes from the outside air inlet 2 to the outside. At this time, when the user performs the suction operation, even if the Q liquid supply device 18 sends a certain amount of the solution into the aerosol generation flow path 6, the amount of the aerosol attracted by the user is unstable. When the temperature of the ceramic heater 12 was raised to 300 ° C and the state was maintained for 10 minutes, an experiment of measuring the temperature at the supply position A was performed. Here, it has been found from the experimental results that the temperature rise of the heat sink cover 20 at the supply position A is suppressed to about 60 ° C. On the other hand, when the heat sink cover 20 is not provided, the temperature at the supply position A also rises to about 160 ° C. Further, the dimensions of the air introduction tube 8, the ceramic heater 12, and the heat dissipation cover 20 used in the experiment are as follows. 8 320811 200932367 Air inlet pipe 8 : ^ 6mm small crotch outer diameter = 1 · 9mm, length = l5mm, thickness = lmm and ceramic heater 12 : 外径 coffee outer diameter = 4mm, length = 30 legs, resistance 値 = 〇 4Ω heat sink 20 : = area = 1160 coffee 2, volume = 412_3 Air guide tube 8 replaces the above heat shield 2 () 2 〇, heat pipe or heat capacity 埒 埒 胥 ... ... 卓 卓 卓 卓 卓 卓. At this time, it is preferable that the heat pipe or the heat sink phase tube 8' is connected in the vicinity of the supply position A. As shown by the 2-point chain line of the first towel, the '10-elite element' or the cooler 74 such as air-cooled or water-cooled is performed when the air introduction pipe 8 is =, and the second embodiment shows the aerosol of the second embodiment. Attractor. When the aspirator of the second embodiment is described, the constituent elements that are the same as those of the constituent elements of the first embodiment are denoted by the same reference numerals and the description thereof will be omitted. The aspirator of the second embodiment includes an opening and closing valve 22 that is disposed in the liquid g path 16. In addition, the aspirator also has the ability to sense the user's inhalation! A pressure-sensing sensor (not shown) for squatting action. When the suction sensing sensor detects the suction operation performed by the user, the opening and closing valve 22 is g. On the other hand, when the suction sensing sensor does not detect the suction operation by the user, the opening and closing valve 22 is maintained in the closed state. Furthermore, the liquid supply device 18 also operates in accordance with a detection signal from the attraction sensing sensor 320811 9 200932367. At this time, the liquid supply device 18 is linked to the suction operation of the user, that is, when the suction sensing sensor outputs the detection signal, a certain amount of the solution is sent from the supply position A to the aerosol generation flow path 6. - At this point in time, when the solution is delivered, the solution is immediately transferred from the supply position A to the ceramic heater 12 to become an aerosol. As described above, when the user does not perform the suction operation, the opening and closing valve 22 is closed. Therefore, there is no doubt that the liquid in the pump chamber of the liquid supply device 18 passes through the external air introduction port 2 or the nozzle 4 and is exposed to the outside air, and the pump chamber is kept in a sealed state. Therefore, the solution in the pump chamber contains a volatile component such as a fragrance, and even if the heat from the ceramic heater 12 is transferred to the solution in the pump chamber, the volatile component is volatilized from the solution, and the volatile component is not released to the outside air. As a result, deterioration of the solution in the pump chamber is effectively prevented. Further, in Fig. 1, the on-off valve 22 is indicated by a two-dot chain line. This means that the opening and closing valve 22 can be used in combination with the heat sink 20 or the cooling device 21. As the on-off valve 22, various commercially available valves can be used. For example, when the liquid line 16 is formed of a rubber tube which is elastically deformable by Q, an opening/closing valve which uses one of the rubber tubes as a valve passage may be used. The opening and closing valve is crushed while elastically deforming the rubber tube to close the valve passage, and the rubber tube is released from the crushing force, and the rubber tube is returned to the original state by the restoring force of the rubber tube. To open the valve passage. An example of such an opening and closing valve is shown in Figs. 3 and 4. The opening and closing valve 24 of Fig. 3 includes a fixing plate 26 and a movable plate 28 spaced apart from the fixing plate 26. The fixing plate 26 may be an inner wall of the outer casing. A pair of valve springs 30 are disposed between the fixed plate 26 and the movable plate 28, and the valve springs 30 such as 10 320811 200932367 are tension coil springs. Each of the valve springs 30 is coupled to both of the fixed plate 26 and the movable plate 28, and the movable plate 28 is biased toward the fixed plate 26, that is, attracted. The rubber tube 32 as the liquid line 16 is heat-resistant and extends through the valve spring 30. In this embodiment, the rubber tube 32 is fixed to the fixing plate 26. As seen from Fig. 3, a pusher 34 is attached to the lower surface of the movable plate 26, and the pusher 34 elastically deforms and crushes the rubber tube 32 by the suction of the movable plate 28. That is, the on-off valve ® 24 at this time is in a state in which the rubber tube 32 is closed, that is, the valve passage is closed. On the other hand, a magnet 36 is attached to the upper surface of the movable plate 28, and a solenoid 38 is disposed above the movable plate 28. From the state shown in Fig. 3, when the electromagnetic coil 38 is excited, the electromagnetic coil 38 attracts the magnet 36 upward. Therefore, the magnet 36 resists the spring pressure of the valve spring 30 and rises together with the movable plate 38 and the pusher 34. As shown in Fig. 4, the pusher 34 is separated from the rubber tube 32, and the q pressure of the rubber tube 32 is released. Crush. As a result, the rubber tube 32 is returned to its original state by its own restoring force, and the valve passage is opened, that is, the opening and closing valve 24 is opened. The on-off valve 24 can also be opened in conjunction with the user's suction operation or the opening operation of the power switch. Fig. 5 and Fig. 6 show an opening and closing valve 40 of a modification. The on-off valve 40 is provided with a fixed wall 42 to which a rubber tube 32 is fixed. Further, the fixed wall 42 may be the inner wall of the outer casing similarly to the fixed plate 26 described above. A push rod 44 is disposed in the vicinity of the rubber tube 32. The pusher 44 extends perpendicularly to the fixed wall 42 relative to 11 320811 200932367 and is supported on the stem bracket 46. More specifically, the lever bracket 46 has a pair of support walls 48a, 48b which are spaced apart from each other in the axial direction of the push rod 44. The push rods 44 are slidably supported by the support walls 48a, 48b, respectively, and are supported by the support walls 48. Further, the push rod 44 has a flange 50 on its outer circumference which is positioned between the pair of support walls 48a, 48b. Between the support wall 48a and the flange 50, a compression coil spring (i.e., a valve spring 52) made of stainless steel is disposed around the push rod 44, and the valve spring 52 functions as the valve spring® 30. . Therefore, the valve spring 52 biases the push rod 44 toward the rubber tube 32 via the intermediate flange 50, that is, pushes it out. Therefore, as shown in Fig. 5, the push rod 44 elastically deforms and collapses the rubber tube 32, whereby the opening and closing valve 40 is closed. On the other hand, between the flange 50 and the support wall 48b, a compression coil spring, that is, a control spring 54, which is formed of a shape-recalling alloy, is disposed. The spring constant of the control spring 54 varies depending on its own temperature. In more detail, the spring constant of the control spring 54 is smaller than the spring constant of the control spring 52 when it is at a surrounding temperature or a low temperature environment of its own low temperature, but when it is at an ambient temperature or its own temperature is higher than a predetermined threshold In the high temperature environment, the spring constant of the control spring 54 is greater than the spring constant of the control spring 52. Moreover, the temperature of the control spring 54 itself can be varied by controlling the supply of power to the control spring 54. When the opening and closing valve 40 is in a low temperature environment, the valve spring 52 is pushed out toward the rubber tube % as described above regardless of the spring pressure of the spring 50 of the control 12 320811 200932367, as shown in Fig. 5 It is in a closed state. At this time, the distance between the flange 50 and the support wall 48b is represented by L1. However, when the opening and closing valve 40 is in a high temperature environment, the spring pressure of the control spring 54 is greater than the spring pressure of the valve spring 52. Therefore, the control sauce 54 pulls the pusher 44 in a direction away from the rubber tube 32. As shown in Fig. 6, the pusher 44 releases the crush of the rubber tube 32, thereby opening the opening and closing valve 4''. The distance between the support wall 48b and the flange 50 at this time is expressed by L2 (> u). As described above, since the opening and closing valve 40 is opened and closed in accordance with the temperature environment, the ceramic heater 12 is kept at the operating temperature, and the opening and closing valve 4 is opened when the opening and closing valve 4 is in a temperature environment due to the heat from the ceramic heater 12. . On the other hand, when the ceramic heater 12 is not operated and the opening and closing valve 4 is in a low temperature environment, the opening and closing valve 40 is closed. At this time, the opening and closing valve 4 is opened and closed in conjunction with the opening and closing operation of the power switch. In addition, the on-off valve 40 is opened and closed by controlling the supply of electric power to the control spring 54 unlike the opening and closing operation of the power switch. Therefore, the opening and closing valve 4 can be opened only when the user performs the suction operation.
